Understanding the LENGTH Function in Looker Studio: A Comprehensive Guide to Counting Characters

Introduction to the Function: LENGTH

Google Data Studio is an online tool primarily used to translate raw data into informative, easy-to-understand reports and dashboards. One of the many functions available within this tool is the 

LENGTH
function.

The 

LENGTH
function in Google Data Studio is used to count the number of characters in any given text. It is a highly practical tool, especially when dealing with textual data or investigating until what extent a specific field or text goes. With the 
LENGTH
function at your service, you can effortlessly figure out the character count, be it in a field, literal text, or an expression that carries at least one field.

The Syntax of the Function

The syntax to use the 

LENGTH
function in Google Data Studio is as straightforward as one might wish. It looks like this:

sql
LENGTH(X)

In the Syntax, 

X
is a placeholder that could represent literal text, a field in your data, or an expression that comprises at least one field.

How Does the Function Work?

The working mechanism of the 

LENGTH
function is very straightforward. All you have to do is replace 
X
in the syntax with the entity you want to check the length for. It can count characters in your specified text, including spaces and punctuation marks.

Examples

Here are a few examples of how the 

LENGTH
function can be used in certain scenarios:

  • Checking ad length for a sales campaign content:

If you wanted to confirm the character count in your ad text for a sales campaign, you would use the 

LENGTH
function like this:

sql
LENGTH("End of Year Sale at XYZ")

This would return 

24
, since there are 24 characters in the text including spaces.

  • Counting characters in an email subject line:

If you are monitoring your sales team's emails and want to check how long their subject lines are, you might use the 

LENGTH
function like this:

sql
LENGTH("Catch the Best Deals at Our Autumn Sale!")

This would return 

38
, as that is the full number of characters including spaces and punctuation marks.

The Limit of the Function

There are no explicit limits to the usage of the 

LENGTH
function. However, you might need to bear in mind the measurable limit that applies to all character data in Google Data Studio - 65,535 characters, which is the maximum length for a string field.

Tips

So as to maximize the utility of the 

LENGTH
function, here are a few tips:

  • Make sure your text doesn't exceed the maximum string length.
  • Keep in mind that the 
    LENGTH
    function also counts spaces and punctuation marks.
  • Use 
    LENGTH
    in conjunction with other Data Studio functions to derive even more value out from your data.

In conclusion, the 

LENGTH
function is a simple but highly valuable tool in Google Data Studio that can help you gain deeper insights into your text data, and therefore make more informed decisions.
